Patented Feb. 1o, 1948 UNITED STATES PATENT GFFICE 2,435,861 SECURITYnoon HOLDER Wylie S. Wlkison, Bayard, N. Mex. Application August 17,1945, Serial No. 610,912 7 Claims. (Cl. 292-341) This invention relatesto a door holder and it is one object of the invention to provide a doorholder adapted to be applied to a door and a door frame and by means ofwhich a door may be held open various degrees and prevented from beingblown shut r open out'of the desired position.

Another object of the invention is to provide a door holder so formedthat it may be actuated with one hand and readily moved to secure orrelease the door.

Another object of the invention is to provide a door holder which, whenapplied to a door and a door frame for use, will not detract from theappearance of the door.

Another object of the invention is to provide a door holder whichconsists of a small number of parts and is quite simple in constructionand may be manufactured at small cost.

The invention is illustrated in the accompanying drawings wherein:

Figure 1 is a view in elevation showing the improved door holder appliedto a door and a door frame in position for use.

Figure 2 is a top plan view of Figure 1.

Figure 3 is a view taken along line 3-3 of Figure 1.

Figure 4 is a fragmentary sectional View taken along line 4-4 ofFigure 1. y

Figure 5 is a fragmentary top plan view of the door holder, an openedposition of the door being indicated by dotted lines.

Figure 6 is a View in elevation of Figure 5.

Figure 7 is a fragmentary sectional View taken along the line I-'I ofFigure 6.

This improved door holder is applied to a door I and the upper portionof a door frame 2 and when so applied constitutes means for holding thedoor opened as far as desired and preventing the door from blowing shut.

A bearing bracket 3 is attached to the upper portion of the door frame Sand has an ear 4 to which an arm or bar 5 is connected by a bolt B. Thearm or bar 5 projects from the door frame and through its outer endpasses a bolt I 'carrying a circular block 8 having teeth about itsperipheral edge face. The bolt I not only connects the block with thearm but also prevents the block from turning relative to the arm. Thelower portion of the bolt projects downwardly from the block and passesthrough a slot 9 formed in a bar I0 longitudinally thereof. The bar I Ilmay therefore have sliding movement radially of the block and alsopivotal movement about the bolt.

The bar I0 is shifted longitudinally in order to move the tooth II of alatch I2 into and out of engagement with the toothed block or disc 8.This is accomplished by door-carried mechanism including rods. I3 andI4. The shaft or rod I3 extends across the upper end of the door andslidably mounted through a bracket I5 carried by the door, the front endof rod I3 being pivoted to an arm I 6 projecting outwardly from theupper end of shaft I4. The shaft or rod I4 extends vertically adjacentthe free side edge of the door and has its lower portion rotatablymounted through a bracket I'I and terminating in a crank handle I8 bymeans of which it may be rotated and impart swinging movement to arm I6for shifting the rod I3 longitudinally. A curved plate or strip I9 issecured to the door and extends transversely of rod I4 between the rodand the door and serves as a wear plate for the rod and also as a brakefor preventing too free turning of the rod. The inner end of rod I3 ispivoted to the inner end of a link or lever 20 pivotally mounted betweenears 2l of a bracket 22 by a pin 23, and this lever 20 carries anupstanding block or post 24 carrying an arm 25 at its upper end. The arm25 projects outwardly from the block 24 and its outer end is pivotallyconnected with the inner or rear end of rod I3 by a pin 26. Shifting ofthe rod I3 longitudinally In one direction will cause the bar I0 l-o beshifted longitudinally in a direction to move the latch I2 away from thedisc 8 and permit free opening or closing movement of the door. Afterthe door has been moved to the desired position. the rod I4 will beturned by its handle I8 to shift the rod I3 longitudinally in theopposite direction and the latch will be moved into engagement with thetoothed disc or keeper and the door will be securely held againstmovement out of the desired position of adjustment. Since the rods I3and I4 extend parallel to and close to the marginal edges of the door,the device may be applied to doors having glass panels, and thisarrangement of rods also disposes the rods and mechanism controlledthereby in such position that they will be inconspicuous and not detractfrom the appearance of the door.
